从失败的更新中恢复

强文本我已经稳定地运行了 18.04.02 Desktop 大约 30 个月。服务器大约 2 周没有开机，所以今天早上开机时它进行了自动安全更新。更新完成后，我运行了更新管理器并收到以下错误消息

显然软件包不一致。我通过运行“sudo nano /etc/apt /sources.list”检查过，我没有任何第三方存储库。至少我是这么认为的。

有没有办法可以恢复到一致的软件包集？没有，我没有最近的备份。我当然已经按照错误消息中的建议进行了操作

机器看上去很稳定，但现在无法更新。这是无可救药的问题吗？

谢谢你的帮助

错误信息

答案1

您的输出包含解决问题所需的信息：

cannot copy extracted data for './usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5' to '/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5.dpkg-new':unexpected end of file or stream

为了便于理解，我们稍微抽象一下……

cannot copy extracted data for X to Y:unexpected end of file or stream

X = './usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5'
Y = '/usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.53.5.dpkg-new'

这是什么意思？

“文件或流意外结束“”的意思就是这个包不完整或损坏了。你必须从本地缓存中删除它，然后让 apt 下载一个新的、新鲜的、完整的包副本。

哪个包裹？

让我们使用 X 提供的路径来向 apt 询问这个问题：

  • 包名称在第二行：libwebkit2gtk-4.0-37
$ dpkg -S /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37
libwebkit2gtk-4.0-37:amd64: /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37

我如何删除损坏的本地包并下载全新的副本？

$ sudo apt clean libwebkit2gtk-4.0-37                 // Delete local
$ sudo apt update
$ sudo apt install --reinstall libwebkit2gtk-4.0-37   // Download fresh

答案2

对我有用的解决方案是执行 sudo apt full-upgrade，其效果是下载损坏软件包的最新副本，然后执行 sudo apt upgrade
